We're a communications agency on a mission: to cause the effect. GMMB opened its doors in 1983 with one goal in mind: to use communications to create real change that would positively impact families, our nation, and our world. We help foundations, non-profits, associations, government and socially conscious corporations achieve their missions of making this world a better place for all of us. We are, at heart, activists. We believe in our clients and are dedicated to the causes they champion.
